If you mean synchronous manner, then the answer is no. A blocking API
would block the event loop and Emacs would appear to be "frozen".
You can however use a process-filter. That's a function that is called
with the data received from the other end. So you always know when data is
ready to process.
If you must use a synchronous mode (e.g. for the the completion code)
then you could use accept-process-output and/or recursive-edit but I
would avoid that as long as possible.
